Bridge A device that connect two networks. Bridges are hardware specific, however they are protocol independent. Bridges operate at Layer 1 and Layer 2 levels. Broadcast Domain device sets that receive broadcast frames originating from any device within a designated set. Routers bind Broadcast domains, because routers do not forward broadcast frames. Broadcasting A method of transmitting packets to all ports on a network. Broadcast Storm An excessive amount of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, overloading network resources or causing the network to time out. For more information about broadcast storms, see "Defining LAG Parameters". C CDB Configuration Data Base. A file containing a device's configuration information. Class of Service Class of Service (CoS). Class of Service is the 802.1p priority scheme. CoS provides a method for tagging packets with priority information. A CoS value between 0-7 is added to the Layer II header of packets, where zero is the lowest priority and seven is the highest. A overlapping transmission of two or more packets that collide. The data transmitted cannot be used, and the session is restarted. CLI Command Line Interface. A set of line commands used to configure the system. For more information on using the CLI, see Using the CLI. Communities Specifies a group of users which retains the same system access rights. CPU Central Processing Unit. The part of a computer that processes information. CPUs are composed of a control unit and an ALU. Glossary 389
